  • Publication number: 20020184865
    Abstract: A walk behind gang mower includes a frame with a plurality of reel-type mowers attached to the frame. The user, along with motors and propulsion wheels, propel the walk behind gang mower forward and rotate the cutting reel. The rear rollers of the reel-type mower unit support the majority of the frame's weight such that the motor indirectly operates the cutting reel by rotation of the propulsion wheel. Movement of the mower rotates the forward drive wheels of the reel type mower(s), which in turn, rotate the cutting reel(s). The user uses a steering controller to adjust the power delivered to the propulsion wheels so that the walk behind gang mower can be easily turned.
